Installation

NOTE: Follow all safety regulations and local codes

when installing this equipment.

1. Determine the mounting location of the enclosure

using the spacing requirements shown in Figure 2.

See Figure 3 and Figure 4 for panel dimensions.

• Minimum spacing between the panel and any

obstruction is 5 inches (127 mm) to the left

(hinged side) and 5 inches (127 mm) to the

right (lock side) (see Figure 5).

• Maximum depth is 11 inches (279.4 mm) to

allow for door clearance.

2. Draw a level line 6 feet (1.8 m) above the floor on

the wall or surface where the enclosure will be

mounted.

3. Affix the adhesive-backed template flush with the

line drawn above.

4. Drill through the template at each marked location

to create the mounting holes.

5. Create three conduit entrances at the top of the

enclosure with a Greenlee punch:

a. Punch one entrance on the right for the power

supply.

b. Punch two entrances towards the center of

the panel for Class 2 and other wires.

6. Mount the panel to the wall. Check the enclosure

to be sure it is level.

NOTE: Separate knockouts should be used for high

voltage and low voltage wiring. Leave at least

a 2-inch (50.8 mm) space between the Class

2 and other wires in the panel.

7. Run conduit and pull wires into the panel. Be sure

to leave enough wire for future changes or

additions.

8. Label each wire.

9. Place the MEC layout sheet in the label pouch

inside the door.

The installation is now complete.
